MOTOR AND PUMP USING THE SAME

摘要

<P>PROBLEM TO BE SOLVED: To provide a motor which can be miniaturized in itself without miniaturizing a motor magnet. Ž<P>SOLUTION: The claw pole type motor includes: a rotor 3 formed by fixing a magnet 2 on a rotating shaft 1; stators 6 oppositely disposed on the outside of the rotor 3 and formed by attaching a winding wire 5 on a yoke 4 for transmitting a rotating drive force to the rotor 3; and a magnetism detection sensor 7 for detecting a magnetic pole magnetized to the magnet 2. In the motor, the magnetism detection sensor 7 is provided on the stator side as a portion where the magnet 2 opposes the stators 6. Specifically, the magnetism detection sensor 7 is provided in the yoke 4 opposing the rotor 3 which is on the outside of the rotor 3. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
